Vishay provides a recommended PCB layout and land pattern in their application note AN10343, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal performance and reliability.
Vishay recommends using a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K. The TIM should be applied evenly and thinly (typically 0.05 mm to 0.10 mm) to the thermal pad of the device. Vishay also provides a list of recommended TIMs in their application note AN10343.
According to Vishay, the maximum allowed voltage derating for PTCCL05H940EBE is 80% of the rated voltage. This means that if the device is rated for 940 V, the maximum allowed voltage derating would be 752 V (80% of 940 V).
To ensure reliability in high-temperature applications, it's essential to follow Vishay's recommended operating conditions and derating guidelines. Additionally, consider using a thermal management system, such as a heat sink or fan, to keep the device temperature within the recommended range. Regular monitoring of the device's temperature and voltage stress can also help prevent premature failure.
The typical lead time and availability for PTCCL05H940EBE can vary depending on the region, distributor, and quantity required. It's recommended to check with authorized distributors, such as Digi-Key or Mouser, for the latest lead times and availability. Vishay's website also provides a 'Check Inventory' feature to help with availability checks.
